Abstract: FIELD: agriculture.  
     SUBSTANCE: group of inventions relates to agriculture. The combined device for mowing, grinding and embedding green manure crops into the soil has a means for mowing the upper part of green manure crops, mounted on the front hitch of the tractor and made in the form of a rotor with a vertical axis of rotation and working elements mounted on it. Each working element is made in form of double steel threads defining a drop-shaped contour, the tip of which is directed to the vertical axis of the rotor and is fixed on it. On the rear hitch of the tractor, a disk tool is mounted, made in form of a frame, on which two batteries of disks are installed in series. The front battery is equipped with sharpened turbo discs and is located perpendicular to the longitudinal axis of the tool for grinding the upper cut and lower uncut parts of green manure crops and their roots. The rear battery is made symmetrically to the longitudinal axis of the tool from the left and right sections with opposite angles of attack, each of which is equipped with spherical disks with trapezoidal teeth, the concavity of which is directed to the longitudinal axis of the tool for embedding crushed green manure crops into the soil. Disclosed is a method for mowing, grinding and embedding green manure crops into the soil. The method includes mowing the upper part of green manure crops. It is carried out by impact action of flexible working elements at an angle of 90 degrees to the vertical axis of the stem. Each flexible working element is made in form of double twisted steel strands. Drop-shaped contour the tip of which is directed to the center of rotation of the rotor is defined. After that the upper cut and uncut lower parts of green manure crops and their roots are ground by turbo discs with a sharpening. Then the ground mass of green manure crops is embedded in the soil by spherical discs with trapezoidal teeth. All three operations (mowing, grinding, embedding green manure crops into the soil) are carried out sequentially by the combined device.  
     EFFECT: reduced energy consumption of technological operations of grinding and embedding of green manure crops into the soil, while improving quality.

Abstract: FIELD: oil-producing and oil-refining industry.  
     SUBSTANCE: invention relates to chemical compositions for the neutralization of hydrogen sulfide and mercaptans in hydrocarbon media, in particular oil, and can be used in the oil-producing and oil-refining industry. The composition for the neutralization of hydrogen sulfide and light mercaptans in hydrocarbon media includes sodium nitrite, an aqueous solution of amines, alkali metal hydroxide and their polysulfides, characterized in that it additionally contains metal compounds of variable valence of a high degree of oxidation, with the following component ratio, wt.%: a composition consisting of a metal compound of variable valence of a high degree of oxidation, selected from the group of Со 3+ , Мо 6+ , Fe 2+ , Fe 3+ , Cu 2+ , and an aqueous solution of alkali metal polysulfide and/or polysulfide of primary or secondary ethanolamines, taken in the mass ratio of the metal compound: polysulfide 1:50-150 3-10%; monoethanolamine, diethanolamine or ethylenediamine 2-5%; alkali metal hydroxide 5-25%; alkali metal nitrite 3-25%; water - the rest. The technical task to which the claimed invention is directed is to increase the efficiency of the process by reducing the consumption of the reagent and reducing the total amount of the water phase supplied to the hydrocarbon media during its simultaneous purification from hydrogen sulfide and mercaptans in one stage. Another task of the invention is to reduce the corrosion activity of oil and oil distillates.  
     EFFECT: proposed composition for purification from hydrogen sulfide and mercaptans is used without air supply, which makes it possible to sharply reduce the time of neutralization reactions of mercaptans, reduce the cost of processing due to the use of cheap reagents, which determines the possibility of its implementation in industrial conditions regardless of the content of hydrogen sulfide and mercaptans in hydrocarbon media.
